You should place each manual and directive that is received by the library in a binder with a vinyl envelope spine  to  accommodate  the  insertion  of  an  identification strip (fig. 3-11). This strip is used to identify the manual or  directive  contained  in  the  binder.  More  than  one publication may be placed in the same binder. The lowest NAVAIR or type directive number should appear first in the spine window followed by the term “thru” and ending with the highest manual number or type  directive.  After  the  publications  are  filed  in binders, the binders are stored on shelves. You should arrange the binders so the manuals are in alphanumeric order by NAVAIR publication number (for an airframe manual,  this  will  automatically  result  in  arrangement by weapon systems). Letter-type technical directives for aircraft or airframes should be filed in individual binders according individual type. SCREENING AND REVIEW OF TECHNICAL DATA All  aircraft  maintenance  organizations  are  in continuous receipt of large quantities of technical information and data. While some of this material is purely  informational,  a  certain  amount  requires immediate or future action. Therefore, it is important that incoming technical data be screened and reviewed by technically competent personnel who are in a position either to advise or to initiate proper action and disposition of the material. Internal routing procedures should ensure that designated personnel are made aware  of  on-hand,  unprocessed  technical  information and data. Figure 3-11.—Identification strip in loose-leaf spine. TECHNICAL PUBLICATIONS RECEIPT AND RECORDING As a technical publication librarian, you must document receipt of all technical publications and changes received by the central library. You should document receipt by using the TPL program and the TPL stamp. For a change or revision of a technical publication already held by activity, you should input the change into the TPL program and use a technical library stamp (obtained through open purchase) to identify the publication itself. The TPL stamp must be used  on  all  publications  and  changes,  including technical   directives,   The   stamp   contains   (as   a minimum) the following information: (1) activity, (2) copy number, and (3) location (QA, P/P, and so forth). Each basic or revised publication should be stamped on the title page that identifies the date of the publication. A technical directive, rapid action change (RAC), or interim rapid action change (IRAC) should be stamped on the first page. If the publication is new, you need to verify its need by checking with the supervisor, QAR, or work center where  the  technical  data  could  be  used.  If  the publication is not needed, you should perform the Return Pubs option in the TPL program. When  a  publication  has  been  requisitioned,  the basic manual and all of its changes are not always received at the same time for various reasons. Because of this you should set aside a location as a hold area for these manuals. Compare the Hold File and the Order Log in the TPL program at least monthly to ensure that the missing manuals and changes are still on order and to determine their status. You should place a note in the Tickler File of the TPL program at 30-day intervals as a reminder to check the Hold File and Order Log. TRANSACTION FILES The  material  maintained  in  the  transaction  files reflects the status of the CTPL. Transaction files consist of the following: Most recent ADRL from NATEC Copies of the last ADRL submission Copies of completed work center audits Copies of completed central library audits Copies of publication requisitions and order logs A current copy of the Dead File 3-20
