Standard state abbreviations have been used for states in the United States.

Capitalization has been standardized and made consistent, and punctuation has been added for consistency and clarification.

Standardized spelling of place names, especially those in foreign countries using other alphabets, has been included in brackets: Hingan [or Khingan]. Most standardized spellings were taken from the U.S. Board on Geographic Names gazetteers, or The Times Atlas of the World. Some could not be found and are left as Harris spelled them, either in his identifications or in his diary.

Harris did a fairly thorough job of identification on his photographs. Many of the earlier larger photographs have identifications written on the back, usually in Harris's handwriting. Some of these photographs have printing instructions for his books or for other purposes, and this is usually not in his handwriting. In some cases a better condition or quality duplicate photograph has replaced the one originally taken out of the album. Some of these have identifications written by a later Photographic Archives processor. These also usually have the old P-333 collection number written on the back. Many photographs have only the Harris identification number written on the back. This Harris number was written by a Photographic Archives processor when the photographs were taken out of the albums. As some of them have this same number on the front, probably in Harris's handwriting, it is assumed that these numbers were transferred from the albums. It should be noted that in the register some Harris numbers are missing. They were missing in the albums. In 1998 the Photographic Archives number was also written, in brackets, on the back of each loose photograph and under the photograph in the albums.

In addition to the identification and numbers on the photographs themselves, many of the negative envelopes (supplied during 1980s processing) had identifications, either typed or handwritten. These identifications were probably taken from the now-missing albums, or possibly from some kind of list made by Harris but not now extant. The original register for MSS 340 indicates that identifications for this first set of photographs is in the negative boxes. Where there is an identification both on the back of the photograph and on a negative envelope, the wording is not always the same. Where there is an actual conflict the most likely identification is given, followed by the other in parentheses: (or ----). In some cases lantern slides had a different or fuller identification than the original photograph. This additional information is added in brackets to the photograph identification.

Identifications in the photograph albums are written on the pages in Harris's handwriting as are his numbers which are written either on the pages or on the actual 35 mm print strips. The Photographic Archives numbers (in brackets) were added to the pages in pencil by the processor in 1999.

Information added to the identifications by the processor, whether additions or corrections, has been enclosed in brackets. Some examples:

a) In some cases a more precise date for an image can be determined from Harris's diary or from other images, occasionally differing from the date he assigned to the image.

b) Unless otherwise indicated, the images were taken in Utah. For those that were not, a state or country has often been added to the identification.

c) In group photographs, especially family photographs, Harris has not often identified individuals. These identifications have been added. When he does identify them, it is not always in standard left to right order.
