"Why did the US intervene in Somalia in 1992?" Need Help with MLA Citations

write an annotated bibliography

I have an assignment to research the topic "Why did the US intervene in Somalia in 1992?", then write an annotated bibliography on sources I used for the research. I have spent upwards of 18 hours on the research and the annotated bibliography, but I have some questions about the MLA citations within the annotated bibliography. Correct MLA citations are 20% of the rubric so I need to get these correct. I have cited the below sources that I have questions about. Can someone confirm my guesses are correct?

I am aware that the citations have a hanging indent. I just can't seem to do this on this forum.

Thanks so much in advance. This grade is very important for me.

1) I have a brochure I found online. I am quite sure this was published as hard copy, but there is no information as to the original publication. Should I treat this as a strictly online source and use the last published date? Below is link to source and what I have so far for citation

history.army.mil/brochures/Somalia/Somalia.htm#intro

Richard Winship Stewart. United States Army in Somalia, 1992-1994. United States Army in Somalia, 1992-1994, Center of Military History, 2003

2) This is case study that is a collection of case studies that, once again, I am quite sure was originally published as hard copy. There is no date of publication since this is an online pdf. What do I do about not having a publication date and how do I handle not having original publication information?.

Lofland, Valerie J. "Somalia: U.S. Intervention and Operation Restore Hope." Case Studies in Policy Making and Implementation

3) This is an online article from Newsweek that was obviously originally published in the hardcopy magazine. The online version has no volume or edition numbers, nor does it have page numbers. How do I cite without this information? Below is link for source and what I have so far for MLA citation:

newsweek/somalias-1992-thanksgiving-reflections-us-humanitarian-intervention-horn-523887

Strong, Robert. "Why the U.S. Intervention in Somalia in 1992 Was an Occasion for Thanksgiving."

You need to follow the rules for electronically sourced information in this instance. There is a specific format for writing these sorts of information. Go to OWL at Purdue and look up their current information for MLA formatting and style guide. Pay particular attention the how they advise that the MLA Works Cited: Electronic Sources (Web Publications) should be formatted. All of the questions that you have will find its answers there. If you feel that the cite does not contain answers, then you will have to be willing to spend at the websites that you listed so that you can gain access to the actual publications which indicate publication dates, pages, volumes, issue numbers, and other pertinent information for your research paper. There is no other way around it.
