This file consists of correspondence with the IEE Library in 1996 to search for bibliographic references to "Barker Codes" and "Barker Sequences". The reply from the IEE Library states that their database [INSPEC] has identified 218 papers published on these subjects since 1969 [when the database started]. Included is a list of 10 bibliographic references from INSPEC and general information regarding the IEE Library's services. There are 8 print-out pages of Barker Sequence and Barker Code from other databases. One copy of 'The historic development of polyphase (Barker) codes, the present state of the art, and some future implications for measurement systems and communications.' by Egbert Jan Reijo Hubach, 1995. One partial letter (recipient unknown) discussing family health and general news but also reference to the enquiry to the IEE Library and the outcome. These items were from folder number 21 in the original deposit.
