The Civic Guard (Garda Síochána) temporary register is the earliest register of recruitment of rank and file members into An Garda Síochána. The volume starts in February 1922 and was taken out of general usage in September 1924 after the recruitment of the first 6,042 members. Not all those entered into the register are successful applicants and unsuccessful applicants are not given a registered number. The volume also records separately the members who joined from Oriel House (the Criminal Intelligence Department) and the latest entry for this section is 16/5/1929. Each entry records the following details: registered number, date of joining, name, address, date of birth, religion, if in I.R.A. - rank, if ex. R.I.C. - rank, if ex. foreign army - rank, height, chest, and remarks. From April 1923 (p. 298) a column was added for knowledge of Irish. The remarks column records general information about the recruits such as dismissal or retirement details, and changes in rank. The remarks column also details the reason why an unsuccessful applicant was rejected. Reasons for rejection include medically unfit, dental problems, and failure to meet literacy, height, or chest measurement requirements.
The Dublin Metropolitan Police (DMP) general register covers recruitment and transfers within the Dublin Metropolitan Police. The first 252 pages of this volume are available through the UCD Digital Library. There are 12,567 entries on these pages, covering the period 1837-1925. Following this period the General Register was taken into use by An Garda Síochána and the remaining pages involve the movement of Gardaí to the Dublin Metropolitan Area. Use of the General Register continued until 1975 although only the entries up to 1925 have been digitised and made available online for data protection reasons. Each entry records the following details: warrant number, name, age, height, trade or occupation, county, parish, post town, previous public service, by whom recommended, divisions attached to, service details (dates, rank, promotions etc.), good service pay, date and cause of removal from the force, reappointment details, and general observations. Religion was added from 1858 (p. 117).
