Memorandum to Mr. T. W. Leavitt Re: Surreptitious Entries 66-8160 th DETAILS: 715 s/o Sas on 4/13/ FO, LNILU canvassed each field office for documents similar to the SAC Folders dealing with entries located in the New York Office. The SAC Foiders contained a number of memoranda showing requests and approvals to conduct entries. The 4/13/76 survey, however, did not specifically include a review of symbol number indexes as part of the instruction to locate documents relating to entries. On 7/28 /76, Deputy Assoc ie eee ek te 5 a | James B, Adams noted that in connection with INTD inguiries into matters concerning surreptitious entries performed by Bureau personnel, all field offices had not been canvassed with instructions to review informant symbol number indexes for evidence of entry activity. As in the case of technical, microphone and live sources, symbol numbers were assigned to surreptitious entries. Symbol number indexes are maintained at the field office level in a confidential informant files unit or similar section. The indexes are not a part of the general office indices. Mr. Adams pointed out on 7/8/76 that by not checking £4018 nfft eee we mae hecre the symbol number indexes in all field offices we may nave created a gap in our efforts to locate material pertaining to entries, and that we should consult with the Department on this problem. A check of indexes presently located in INTD - indexes dealing with technical, microphone, trash and mail coverage, and certain “anonymous source” contacts - fails to suggest field offices will have symbol number index cards in addition to those sent by them for indexing to Headquarters. Nevertheless, Mr. Gardner was advised of the above on 7/8/76. He said he would consider our proposal to go to the field offices, and advise of his decision at a later date.
