Club were written and filed. This brings the subject index up to 
date to July. 
3. Another worthwhile project was accomplished by one of these 
workers who looked through the entire set of Botanisches Central- 
blatt (1880-1932) for biographical material and made cards for 
individual biographies which have been filed in the library cata- 
logue. This enables us to locate at once obituary notices, dates of 
birth and death, portraits and bibliographies of many botanists 
who might otherwise be difficult to trace. If possible this work 
should be supplemented by similar references from all our periodi- 
cals. 
4. By far the most ambitious work undertaken this year was the 
making of an author index for the last four volumes of Botanical 
Abstracts, vol. 12-15 inclusive, which were published and bound 
with no indices. Through the courtesy of Dr. Jacob R. Schramm, 
fue 
the present editor of Biological Abstracts (into which was mergec 
the former Botanical Abstracts) we obtained slips, forms, mate- 
rial, and advice regarding making indices to conform to those of 
previous volumes. The idea is to acquire a useable author 
list for ourselves for the present, which could be turned over to 
the publishers when they were prepared to print it, thus benefiting 
them as well. Two volumes, 12 and 13, are completely indexed, 
the slips revised, alphabetized, and ready for use. Author indices 
to vols. 14 and 15 have been typed, and are being held for revision. 
5. Last spring the librarian, Mr. Foss, worked out a scheme of 
classification in order to catalogue by subject the lantern. slides 
which have been made from the Brooklyn Botanic Garden nega- 
tives. This scheme is still waiting for approval, but meanwhile, 
one of the untrained workers has copied the existing catalogue 
cards pertaining to the slides, which should greatly facilitate the 
work of re-arrangement. 
6. One of the minor, but necessary, pieces of work was the 
thorough cleaning, dusting, and rubbing down of the leather bind- 
ings of the books on the shelves. This is done to protect and 
preserve the bindings and to prevent the dust from sifting through 
the pages to their detriment.
