1Lor, P. ; Wiles, B. ; Britz, J.: Re-thinking information ethics : truth, conspiracy theories, and librarians in the COVID-19 era.
In: Libri. 71(2021) no.1, S.1-14.
Abstract: The COVID-19 pandemic is an international public health crisis without precedent in the last century. The novelty and rapid spread of the virus have added a new urgency to the availability and distribution of reliable information to help curb its fatal potential. As seasoned and trusted purveyors of reliable public information, librarians have attempted to respond to the "infodemic" of fake news, disinformation, and propaganda with a variety of strategies, but the COVID-19 pandemic presents a unique challenge because of the deadly stakes involved. The seriousness of the current situation requires that librarians and associated professionals re-evaluate the ethical basis of their approach to information provision to counter the growing prominence of conspiracy theories in the public sphere and official decision making. This paper analyzes the conspiracy mindset and specific COVID-19 conspiracy theories in discussing how libraries might address the problems of truth and untruth in ethically sound ways. As a contribution to the re-evaluation we propose, the paper presents an ethical framework based on alethic rights-or rights to truth-as conceived by Italian philosopher Franca D'Agostini and how these might inform professional approaches that support personal safety, open knowledge, and social justice.

2Thelwall, M. ; Thelwall, S.: ¬A thematic analysis of highly retweeted early COVID-19 tweets : consensus, information, dissent and lockdown life.
In: Aslib journal of information management. 72(2020) no.6, S.945-962.
Abstract: Purpose Public attitudes towards COVID-19 and social distancing are critical in reducing its spread. It is therefore important to understand public reactions and information dissemination in all major forms, including on social media. This article investigates important issues reflected on Twitter in the early stages of the public reaction to COVID-19. Design/methodology/approach A thematic analysis of the most retweeted English-language tweets mentioning COVID-19 during March 10-29, 2020. Findings The main themes identified for the 87 qualifying tweets accounting for 14 million retweets were: lockdown life; attitude towards social restrictions; politics; safety messages; people with COVID-19; support for key workers; work; and COVID-19 facts/news. Research limitations/implications Twitter played many positive roles, mainly through unofficial tweets. Users shared social distancing information, helped build support for social distancing, criticised government responses, expressed support for key workers and helped each other cope with social isolation. A few popular tweets not supporting social distancing show that government messages sometimes failed. Practical implications Public health campaigns in future may consider encouraging grass roots social web activity to support campaign goals. At a methodological level, analysing retweet counts emphasised politics and ignored practical implementation issues. Originality/value This is the first qualitative analysis of general COVID-19-related retweeting.

4Stock, M. ; Stock, W.G.: Medizininformationen : Literaturnachweise, Volltexte und klinische Entscheidungen aus einer Hand.
In: Password. 2004, H.11, S.20-28.
Abstract: Ovid Technologies speist sich aus unterschiedlichen Unternehmensgeschichten; die Erfahrungen von BRS, SilverPlatter, Ovid und Wolters-Kluwer ergänzen sich in den derzeit betriebenen zwei Plattformen Ovid und SilverPlatter. Ovid spricht vor allem praktizierende wie forschende Spezialisten in der medizinisch-biowissenschaftlichen Sparte an, während SilverPlatter eher auf den gesamten akademischen Betrieb abzielt. Wir konzentrieren uns in diesem Artikel auf die Ovid-Plattform und vernachlässigen SilverPlatter. Das Interessante an Ovid ist die Einheit von bibliographischen Nachweisdaten, Volltexten und praxisrelevanten klinischen Entscheidungshilfen. U.E. lohnt die Retrievaloberfläche von Ovid und die hier praktizierte durchgehende Verlinkung von Nachweisen und Volltexten und von Volltexten untereinander einer näheren Betrachtung. Unsere Ergebnisse stützen sich auf den Fragebogen, Gespräche mit Jens Gräßler, National Sales Manager Germany, vom deutschen Ovid-Büro in Berlin sowie auf Tests im März und im April 2004.

5Ovid : Recherche in Bibliothekskatalogen leicht gemacht.
In: BuB. 55(2003) H.9, S.539-540.
Abstract: Ovid, Anbieter von Informationslösungen, erleichtert die Recherche in externen und internen Datenbanken. Mit dem Links@Ovid Service, der in das OvidWeb-Gateway integriert ist, haben Bibliothekare medizinischer Büchereien, Klinikärzte und Forscher die ideale Lösung für ihre Suchen. Die Anwendung verlinkt mehr als 100 bibliographische Datenbanken von Ovid mit elektronischen Volltext-Datenbanken. Eine verfeinerte Suche, die nur Volltext-Ergebnisse anzeigt, ist ebenso möglich - egal, ob es sich dabei um Titel von Verlagen oder von ContentAggregatoren handelt. Links@Ovid verlinkt auch lokale Print-Ressourcen über die Online-Bestandskataloge von Bibliotheken oder Dokumentenlieferdiensten. Die Vorteile der Ovid Lösungen für Informationsmanager liegen aufder Hand: Neben umfangreichen Ressourcen können sie ihren Arbeitsablauf wesentlich effizienter gestalten und unterbrechungsfreier arbeiten. Wie der Ovid LinkSolver filtert Links@Ovid Volltext-Ergebnisse aus den Suchresultaten der bibliographischen Ovid Datenbank heraus. Administratoren können dank eines integrierten Werkzeugs problemlos Journal-Listen aus einem Opac oder anderen Serials-Datenbanken importieren. Das Administrationswerkzeug ist einfach zu handhaben und erlaubt den direkten Zugriff von der OvidWeb-Gateway-Benutzeroberfläche aus. Inhalte lassen sich direkt mit den Angaben verlinken, die in Journals@Ovid zitiert sind.

6Jett, M. ; Reuse, B. ; Kessling, G.: Implementation of an online database for tables of contents of books.
In: Electronic library. 16(1998) no.2, S.123-130.
Abstract: Many small libraries do not have the resources to build a holdings database but the availability of affordable scanners and improved OCR software has made possible a new approach for creating online databases. Describes the work undertaken at the Otto Hahn Library of the Max Planck Institute for Biophysical Chemistry, Germany, to create a database consisting of the titles, bibliographic descriptions and contents tables of books acquired by the library. The book information and table of contents pages are scanned and converted to text using OCR software. A computer program is used to extract as much information as possible, in particular from the CIP data with corrections and missing information being supplied manually. Finally, the information, which consists of: title; author; ISBN; publication year; call number; series; language; and other relevant information for books, as well as the entire table of contents, is stored and added to an Ovid database using the Ovid Local Loader software. Pays particular attention to the algorithm used to extract specific information from the CIP data. 2 OCR software packeges have been tested: OmniPage Pro 7.0 and FineReader 3.0. Experience has shown that FineReader is better at character recognition and retains the formatting better but OmniPage Pro is easier to train to recognize special characters

8Hallet, K.S.: Separate but equal? : A system comparison study of MEDLINE's controlled vocabulary MeSH.
In: Bulletin of the Medical Library Association. 86(1998) no.4, S.491-495.
Abstract: Reports results of a study to test the effect of controlled vocabulary search feature implementation on 2 online systems. Specifically, the study examined retrieval rates using 4 unique controlled vocabulary search features (Explode, major descriptor, descriptor, subheadings). 2 questions were addressed; what, if any, are the general differences between controlled vocabulary system implementations in DIALOG and Ovid; and what, if any are the impacts of each on the differing controlled vocabulary search features upon retrieval rates? Each search feature was applied to to 9 search queries obtained from a medical reference librarian. The same queires were searched in the complete MEDLINE file on the DIALOG and Ovid online host systems. The unique records (those records retrieved in only 1 of the 2 systems) were identified and analyzed. DIALOG produced equal or more records than Ovid in nearly 20% of the queries. Concludes than users need to be aware of system specific designs that may require differing input strategies across different systems for the same unique controlled vocabulary search features. Making recommendations and suggestions for future research

9Cavanaugh, B.B.: ¬The Ovid Java client interface : a comparison with the Ovid Web Gateway and Windows Client interface.
In: Medical reference services quarterly. 17(1998) no.4, S.1-15.
Abstract: The Ovid Java interface is compared with the Ovid Web Gateway and Ovid Windows Client, focusing on functionality from the user's perspective. The Java version draws upon both earlier Web and Windows versions, thus combining the worlds of the Web and application programs. It is concluded that Ovid Java offers enhanced functionality and requires high-end hardware and browser software to run well. Additional enhancements are forthcoming, some dependent upon the further development of Sun Microsystems' Java programming language

15Schoonbaert, D.: SPIRS, WinSPIRS, and OVID : a comparison of three MEDLINE-on-CD-ROM interfaces.
In: Bulletin of the Medical Library Association. 84(1996) no.1, S.63-70.
Abstract: Reports results of a study to compare 3 CD-ROM interfaces working on MEDLINE databases: SPIRS (ver. 3.11) and WinSPIRS (ver. 1.0) from SilverPlatter and OVID (ver. 3.0, DOS and WINDOWS interfaces) from CD Plus Technologies (now OVID Technologies). Though the database is the same, there are substantial differences between the interfaces in the way the data is presented and can be searched. Discusses these different approaches and includes a detailed comparative table. Concludes that all 3 interfaces are good yet none of them is perfect; each has desirable and unfortunate features. Together, they offer an enormous range of possibilities. Users would benefit if most of the better features listed (such as easy menu, free text retrieval, pre exploded thesaurus terms) were implemented in future versions of these interfaces and if system operators were given greater latitude to determine the system defaults appropriate to their specific situations and customers. A full, comparative table of features are presented for SPIRS, WinSPIRS, OVID(DOS) and OVID(Windows)
