BROWSE these pages for reference works like bibliographies, dictionaries, and encyclopedias. Use these resources to become familiar with key works and scholarly trends.
Remember to look at general reference works and reference books beyond History of Science. See: Reference Materials (by Laurie Scrivener, History/Area Studies Librarian).
Can't find an entry on your topic in a reference book? Then check in index at the back.
For example, the encyclopedia Medieval Science, Technology, and Medicine does not have a separate entry on "rainbow." But, in the index you will find citations to pages where the rainbow is discussed:
These page numbers after Rainbow lead you to entries on "Ibn al-Haytham," "Optics and Catoptrics," and "Theodoric of Freiberg"
Science encyclopedias sometimes include historical entries written by prominent historians (for example, see the numerous entries on the history of geology by D. Oldroyd in Encyclopedia of Geology).
