We the people : the American people and their government / [text, Division of Political History]. (OCLC #1288911)
In a SuDoc classification number, the cutter for the title is based on the first significant word in the title that denotes the subject of the resource, also excluding “catch phrases”. For this resource, “We the people” is skipped, and the cutter is based on the word American:
Behavior and neurology of lizards : an interdisciplinary colloquium / edited by Neil Greenberg and Paul D. MacLean. (OCLC #4571831)
In a SuDoc classification number, the cutter for the title is based on the first significant word in the title that denotes the subject of the resource. This excludes words common to government documents (“Symposium”, “Report”), to the particular agency (“Forest”, “Wood” for the Forest Service).
This resource was cuttered on the word Lizards even though it’s the fifth word in the title.
Aliens in the United States (number of aliens in the United States, by States, counties, and nationalities, who reported under the Immigration and nationality act during January 1965) Prepared for the Subcommittee on Immigration and Naturalization of the Committee on the Judiciary, United States Senate. (OCLC #184920)
I know now that the monthly catalog record for this title says “Aliens in United States” (missing a word), which is why my full title searches were not finding it. I continued my search using the SuDoc number instead.
I initially misread the second cutter in the SuDoc, first looking too quickly and seeing only an “A” with a flourish, and then recognizing it as “Ae”. That also turned out to be incorrect.
I had found the OCLC record already (no SuDoc number), so used the Find in a Library feature to check what other people had as its SuDoc number in their government document collections. I found a library with a slight different SuDoc number (another variant!):
before finally finding the correct one:
Y 4.J 89/2:AL 4/5
and spotting that those letters must start the cutter for ALiens.
Otsuchi : moving forward from the Great East Japan Earthquake and Tsunami : a photo essay of a small town in Japan / Meiji Gakuin University Volunteer Center ; editing and design, Cody Rapley. (OCLC #889095202)
Most call numbers in Library of Congress Classification follow a pretty standard pattern: 1-3 capital letters, a number (possibly with a decimal part), one or two cutters, and sometimes a year. One exception is in call numbers for books about events like earthquakes, where the class number also includes a year for the occurrence (in addition to the year that might be in the “item number” part of the call number). For example, HV599 is for general works about earthquakes, but HV600 is for works about specific earthquakes by date, then subarranged by place, A-Z, and by author, A-Z.
This title about the 2011 Tōhoku earthquake and tsunami, so the first cutter is for Tōhoku, the region where that earthquake took place. The second cutter is for the main entry, which in this case is the title. This forms the call number:
Freedom 7 : the historic flight of Alan B. Shepard, Jr. / Colin Burgess. (OCLC #857972968)
Call numbers with three cutters are pretty unusual in the Library of Congress classification schedule; I mainly see them in G (maps).
If you are using a class number that already has two cutters specified, such as TL789.8.U6A5 (Space travel, United States, Apollo Program), you still need to extend the call number to sort items by main entry. Rather than adding a third cutter (starting with another letter) just extend the second cutter with numbers.
For this title (about a mission from Project Mercury), I started by identifying the second cutter used for that project (M4) and checking the LC catalog to shelflist, ordering by main entry. Library of Congress already has a title in their collection about this topic by this author (“Selecting the Mercury seven”) with call number:
TL789.8.U6 M428 2011
so I shifted the cutter yet again to also order by title:
Most of our manga is classified under PN6790.J34; that is, PN6790 for comic books/strips by region or country (other countries), cuttered by .J3 for Japan. The table for this classification says that you can append 3 to further cutter by author, or append 4 to cutter by title, specifying that title is the preferred way.
This particular title (Yotsuba & !) has the call number:
PN6790.J34 Y68 2003
We also have some volumes of the English translation under:
