If you are doing historical research in the sciences, PUL has two new acquisitions that will be of great benefit:
BIOSIS Previews/Biological Abstracts Archive: 1926-1968
The BIOSIS Archive delivers all the bibliographic records from 49 Biological Abstracts print volumes 1926 to 1968. It consists of 1.8 million records relevant to working biologists, from journals, patents, conference reports and books, and in fully indexed and searchable form. With more than 15 million records, Biosis is the most comprehensive index of journals, meetings, conferences, and symposia in the life sciences ranging from 1926 to the present. Although this is not a full-text article database, our PULinks system conveniently links you to the full-text
Also, we now subscribe to BIOSIS via the Web of Knowledge Platform. This change enables researches to link directly to the cited reference data in Web of Science.
Web of Science Historic Backfiles: 1900-1944
The ISI Century of Science Project made available more than 850,000 of the most influential, important and useful articles from 262 scientific journals from 1900 - 1944. This adds 44 years on to the already robust Web of Science database. Navigate backward in time using the Cited References feature to uncover the research that influenced an author’s work. Navigate forward in time using the Times Cited feature to discover the impact a paper or other published item has had on current research.
