    Abstract
    This article will showcase the aims and research goals of the project entitled "Transforming Libraries and Archives through Crowdsourcing", recipient of a 2016 Institute for Museum and Library Services grant. This grant will be used to fund the creation of four bespoke text and audio transcription projects which will be hosted on the Zooniverse, the world-leading research crowdsourcing platform. These transcription projects, while supporting the research of four separate institutions, will also function as a means to expand and enhance the Zooniverse platform to better support galleries, libraries, archives and museums (GLAM institutions) in unlocking their data and engaging the public through crowdsourcing.

    Abstract
    How sharing the mundane details of daily life did not start with Facebook, Twitter, and YouTube but with pocket diaries, photo albums, and baby books. Social critiques argue that social media have made us narcissistic, that Facebook, Twitter, Instagram, and YouTube are all vehicles for me-promotion. In The Qualified Self, Lee Humphreys offers a different view. She shows that sharing the mundane details of our lives?what we ate for lunch, where we went on vacation, who dropped in for a visit?didn't begin with mobile devices and social media. People have used media to catalog and share their lives for several centuries. Pocket diaries, photo albums, and baby books are the predigital precursors of today's digital and mobile platforms for posting text and images. The ability to take selfies has not turned us into needy narcissists; it's part of a longer story about how people account for everyday life. Humphreys refers to diaries in which eighteenth-century daily life is documented with the brevity and precision of a tweet, and cites a nineteenth-century travel diary in which a young woman complains that her breakfast didn't agree with her. Diaries, Humphreys explains, were often written to be shared with family and friends. Pocket diaries were as mobile as smartphones, allowing the diarist to record life in real time. Humphreys calls this chronicling, in both digital and nondigital forms, media accounting. The sense of self that emerges from media accounting is not the purely statistics-driven ?quantified self,? but the more well-rounded qualified self. We come to understand ourselves in a new way through the representations of ourselves that we create to be consumed.

    Abstract
    This paper discusses an approach of collecting qualitative data on human information behaviour that is based on mining web data using search engines. The approach is technically the same that has been used for some time in webometric research to make statistical inferences on web data, but the present paper shows how the same tools and data collecting methods can be used to gather data for qualitative data analysis on human information behaviour.

    Abstract
    University libraries invest a massive amount of resources in digitizing information for the Web, yet there is growing concern that much of this information is being underutilized. The present study uses the technology acceptance model (TAM) to investigate university library website resources (ULWR) usage. We categorize users based on academic roles and then analyze them as subgroups in order to observe different adoption patterns across groups. A total of 299 usable responses was collected from four different universities and across three populations: undergraduate, master, and doctoral student/faculty groups. The findings show that different library users indeed access ULWR for different reasons, resulting in a need for tailored managerial efforts. Overall, the extended TAM explains undergraduate students' usage best; the explanatory power of the model is significantly lower for the doctoral student/faculty group. Some of the findings challenge results reported in TAM research in other fields. The unexpected findings may result from the application of the model to a different context. Detailed theoretical implications and managerial guidance are offered.

    Abstract
    The Digital Public Library of America brings together the riches of America's libraries, archives, and museums, and makes them freely available to the world. In order to do this, DPLA has had to build elements of the national digital platform to connect to those institutions and to serve their digitized materials to audiences. In this article, we detail the construction of two critical elements of our work: the decentralized national network of "hubs," which operate in states across the country; and a version of the Hydra repository software that is tailored to the needs of our community. This technology and the organizations that make use of it serve as the foundation of the future of DPLA and other projects that seek to take advantage of the national digital platform.

    Abstract
    This is a practical guide to using web metrics to measure impact and demonstrate value. The web provides an opportunity to collect a host of different metrics, from those associated with social media accounts and websites to more traditional research outputs. This book is a clear guide for library and information professionals as to what web metrics are available and how to assess and use them to make informed decisions and demonstrate value. As individuals and organizations increasingly use the web in addition to traditional publishing avenues and formats, this book provides the tools to unlock web metrics and evaluate the impact of this content. The key topics covered include: bibliometrics, webometrics and web metrics; data collection tools; evaluating impact on the web; evaluating social media impact; investigating relationships between actors; exploring traditional publications in a new environment; web metrics and the web of data; the future of web metrics and the library and information professional. The book will provide a practical introduction to web metrics for a wide range of library and information professionals, from the bibliometrician wanting to demonstrate the wider impact of a researcher's work than can be demonstrated through traditional citations databases, to the reference librarian wanting to measure how successfully they are engaging with their users on Twitter. It will be a valuable tool for anyone who wants to not only understand the impact of content, but demonstrate this impact to others within the organization and beyond.

    Abstract
    Aufgrund der so großen Bedeutung von Privatheit im Internet hat acatech, die Deutsche Akademie der Technikwissenschaften, 2011 ein Projekt initiiert, das sich mit dem Privatheitsparadoxon wissenschaftlich auseinandersetzt. In dem Projekt werden Empfehlungen entwickelt, wie sich eine Kultur der Privatheit und des Vertrauens im Internet etablieren lässt, die es ermöglicht, das Paradoxon aufzulösen. Wir verwenden hier den Begriff der Privatheit. Er deutet an, dass hier nicht nur der räumliche Begriff Privatsphäre gemeint ist, sondern auch das im europäischen Kontext wichtige Konzept der informationellen Selbstbestimmung einbezogen ist. Dieser Band legt die Ergebnisse der ersten Projektphase vor: eine Bestandsaufnahme von Privatheit im Internet aus verschiedenen Blickwinkeln. Kapitel 1 stellt die Wünsche und Befürchtungen von Internetnutzern und Gesellschaft im Hinblick auf ihre Privatheit vor. Sie wurden mithilfe sozialwissenschaftlicher Methoden untersucht. Ergänzend dazu untersucht das zweite Kapitel Privatheit im Cyberspace aus ethischer Perspektive. Das dritte Kapitel widmet sich ökonomischen Aspekten: Da viele Onlinedienstleistungen mit Nutzerdaten bezahlt werden, ergibt sich die Frage, was dies sowohl für den Nutzer und Kunden als auch für die Unternehmen bedeutet. Kapitel 4 hat einen technologischen Fokus und analysiert, wie Privatheit von Internettechnologien bedroht wird und welche technischen Möglichkeiten es gibt, um die Privatheit des Nutzers zu schützen. Selbstverständlich ist der Schutz von Privatheit im Internet nicht nur ein technisches Problem. Deshalb untersucht Kapitel 5 Privatheit aus rechtlicher Sicht. Bei der Lektüre der fünf Kapitel wird dem Leser sofort die Komplexität der Frage von Privatheit im Internet (Internet Privacy) bewusst. Daraus folgt die unbedingte Notwendigkeit eines interdisziplinären Ansatzes. In diesem Sinne wird die interdisziplinäre Projektgruppe gemeinsam Optionen und Empfehlungen für einen Umgang mit Privatheit im Internet entwickeln, die eine Kultur der Privatheit und des Vertrauens im Internet fördern. Diese Optionen und Empfehlungen werden 2013 als zweiter Band dieser Studie veröffentlicht.

    Abstract
    Purpose - This study aims to investigate the discourses surrounding the provision of internet access in Singapore through the public library system and to consider what the government, librarians and members of the public consider are the legitimate uses of the internet in Singapore's public libraries, how these compare with what the librarians see as their role in facilitating access and to what extent the internet as an educational tool features in public libraries according to users. Design/methodology/approach - A discourse analysis of public documents and semi-structured interviews with ten senior librarians, managers, and 40 members of the public were conducted. Observation was also conducted of library users and of their usage at the computer terminals in the library. Findings - Findings from the study throw up very different definitions of what constitutes learning through the internet within the context of a public library. This reinforces conclusions from previous studies that what is termed learning through the internet is variously constructed, and understood in multiple ways. This defies what is often presented of the internet as a technical quick fix of policy makers to help its population leap frog into the future. Research limitations/implications - While the study provided a glimpse into the discourse surrounding the internet in one country, similar work should be carried in more Asian countries to provide a more comprehensive survey of the region and compare this with findings conducted in an Occidental setting. Originality/value - The study provides an Asian perspective that complements findings on the various discourses that had surrounded internet technology in the USA and Europe. It also calls for a new spirit of awareness on the part of librarians to the views of library users with regard to internet access.

    Abstract
    In Digital Methods, Richard Rogers proposes a methodological outlook for social and cultural scholarly research on the Web that seeks to move Internet research beyond the study of online culture. It is not a toolkit for Internet research, or operating instructions for a software package; it deals with broader questions. How can we study social media to learn something about society rather than about social media use? How can hyperlinks reveal not just the value of a Web site but the politics of association? Rogers proposes repurposing Web-native techniques for research into cultural change and societal conditions. We can learn to reapply such "methods of the medium" as crawling and crowd sourcing, PageRank and similar algorithms, tag clouds and other visualizations; we can learn how they handle hits, likes, tags, date stamps, and other Web-native objects. By "thinking along" with devices and the objects they handle, digital research methods can follow the evolving methods of the medium. Rogers uses this new methodological outlook to examine the findings of inquiries into 9/11 search results, the recognition of climate change skeptics by climate-change-related Web sites, the events surrounding the Srebrenica massacre according to Dutch, Serbian, Bosnian, and Croatian Wikipedias, presidential candidates' social media "friends," and the censorship of the Iranian Web. With Digital Methods, Rogers introduces a new vision and method for Internet research and at the same time applies them to the Web's objects of study, from tiny particles (hyperlinks) to large masses (social media).

    Abstract
    The debate on Facebook raises questions about the use and users of this information service. This collected volume gathers a broad spectrum of social science and information science articles about Facebook.Facebook has many facets, and we just look forward above all to the use and users. The facet of users has sub-facets, such as different age, sex, and culture. The facet of use consists of sub-facets of privacy behavior after the Snowden affair, dealing with friends, unfriending and becoming unfriended on Facebook, and possible Facebook addiction. We also consider Facebook as a source for local temporary history and respond to acceptance and quality perceptions of this social network service, as well. This book brings together all the contributions of research facets on Facebook. It is a much needed compilation written by leading scholars in the fields of investigation of the impact of Web 2.0. The target groups are social media researchers, information scientists and social scientists, and also all those who take to Facebook topics.

    Abstract
    Recent work by Evans, Cordova, and Sipole (2014) reveals that in the two months leading up to the 2012 election, female House candidates used the social media site Twitter more often than male candidates. Not only did female candidates tweet more often, but they also spent more time attacking their opponents and discussing important issues in American politics. In this article, we examine whether the female winners of those races acted differently than the male winners in the 2012 election, and whether they differed in their tweeting-style during two months in the summer of 2013. Using a hand-coded content analysis of every tweet from each member in the U.S. House of Representatives in June and July of 2013, we show that women differ from their male colleagues in their frequency and type of tweeting, and note some key differences between the period during the election and the period after. This article suggests that context greatly affects representatives' Twitter-style.

    Abstract
    The microblogging site Twitter generates a constant stream of communication, some of which concerns events of general interest. An analysis of Twitter may, therefore, give insights into why particular events resonate with the population. This article reports a study of a month of English Twitter posts, assessing whether popular events are typically associated with increases in sentiment strength, as seems intuitively likely. Using the top 30 events, determined by a measure of relative increase in (general) term usage, the results give strong evidence that popular events are normally associated with increases in negative sentiment strength and some evidence that peaks of interest in events have stronger positive sentiment than the time before the peak. It seems that many positive events, such as the Oscars, are capable of generating increased negative sentiment in reaction to them. Nevertheless, the surprisingly small average change in sentiment associated with popular events (typically 1% and only 6% for Tiger Woods' confessions) is consistent with events affording posters opportunities to satisfy pre-existing personal goals more often than eliciting instinctive reactions.

    Abstract
    Online communities are becoming an important tool in the communication and participation processes in our society. However, the most widespread applications are difficult to use for people with disabilities, or may involve some risks if no previous training has been undertaken. This work describes a novel social network for cognitively disabled people along with a clustering-based method for modeling activity and socialization processes of its users in a noninvasive way. This closed social network is specifically designed for people with cognitive disabilities, called Guremintza, that provides the network administrators (e.g., social workers) with two types of reports: summary statistics of the network usage and behavior patterns discovered by a data mining process. Experiments made in an initial stage of the network show that the discovered patterns are meaningful to the social workers and they find them useful in monitoring the progress of the users.

    Abstract
    Recent research has involved identifying communities in networks. Traditional methods of community detection usually assume that the network's structural information is fully known, which is not the case in many practical networks. Moreover, most previous community detection algorithms do not differentiate multiple relationships between objects or persons in the real world. In this article, we propose a new approach that utilizes social interaction data (e.g., users' posts on Facebook) to address the community detection problem in Facebook and to find the multiple social groups of a Facebook user. Some advantages to our approach are (a) it does not depend on structural information, (b) it differentiates the various relationships that exist among friends, and (c) it can discover a target user's multiple communities. In the experiment, we detect the community distribution of Facebook users using the proposed method. The experiment shows that our method can achieve the result of having the average scores of Total-Community-Purity and Total-Cluster-Purity both at approximately 0.8.

    Abstract
    Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

    Abstract
    Online discussion forums have become a popular medium for users to discuss with and seek information from other users having similar interests. A typical discussion thread consists of a sequence of posts posted by multiple users. Each post in a thread serves a different purpose providing different types of information and, thus, may not be equally useful for all applications. Identifying the purpose and nature of each post in a discussion thread is thus an interesting research problem as it can help in improving information extraction and intelligent assistance techniques. We study the problem of classifying a given post as per its purpose in the discussion thread and employ features based on the post's content, structure of the thread, behavior of the participating users, and sentiment analysis of the post's content. We evaluate our approach on two forum data sets belonging to different genres and achieve strong classification performance. We also analyze the relative importance of different features used for the post classification task. Next, as a use case, we describe how the post class information can help in thread retrieval by incorporating this information in a state-of-the-art thread retrieval model.

    Abstract
    All text is ephemeral. Some texts are more ephemeral than others. The web has proved to be among the most ephemeral and changing of information vehicles. The research note revisits Koehler's original data set after about 20 years since it was first collected. By late 2013, the number of URLs responding to a query had fallen to 1.6% of the original sample. A query of the 6 remaining URLs in February 2015 showed only 2 still responding.
