that D. marinum is present in both locations. 

 Also, growth within the laboratory is slower 

 than that in the lagoon, and finally, as far as 

 we know, a G. monilata bloom occurs every 

 summer. We feel that the variation in growth 

 rates between the two locations would not 

 necessarily affect the suitability of the lab- 

 oratory because many experiments are not 

 concerned with rapid growth. G. monilata , as 



we have shown, can completely disrupt an 

 experiment. Therefore, because of the regu- 

 larity of blooms of this organism and also 

 the presence of D. marinum , we conclude 

 that the waters in the lagoon and in our 

 laboratory are suitable only for short-term 

 oyster experiments,

LIBRARY 



The use of library services was greater 

 during fiscal year 1965 than in previous 

 years. Information and materials were sup- 

 plied to the Laboratory staff, to individuals 

 outside the Government, and to other libraries. 

 The number of requests for interlibrary loans 

 remained about the same as in the previous 

 year. In addition to the processing of current 

 acquisitions, more than half of the reclassifica- 

 tion project was accomplished, and the subject 

 index for recently acquired reprints was 

 completed. The library participated in the 

 1965 edition of the Texas List of Scientific 

 and Technical Serial Publications. The weekly 

 list of library acquisitions was continued for 

 distribution to the staff and to selected labora- 

 tories. 



The demand for library materials by the 

 Laboratory staff required certain changes in 

 the loan regulations. A revised charging sys- 

 tem and limitations on the loan period for 

 selected groups of material were set up so 

 that the publications would be more readily 

 available to the entire staff. 



In June 1965, the library facilities were 

 made available to students attending the sum- 

 mer sessions of Texas A&M University at 

 the A&M Marine Laboratory, Galveston, and 

 we are providing instruction in the use of 

 the library and reference service for about 

 30 students attending each 6-wk. session. 



In October 1964, the librarian visited the 

 other laboratory libraries of Region 2 to re- 

 view their library classification systems as 

 a part of a Regional management improve- 

 ment project. At frequent intervals during 

 the year, the librarian assisted the staff 

 of the A&M Marine Laboratory in library 

 procedures,
