APA citation - parenthethical with page number and textual

Question

I need my text as following.

It was raining (De Silva & Lee, 2018). There was a cat (Kahouli & Maktouf, 2015, p. 12). Baier, Yotov, and Zylkin (2019) said that the cat was running.

First, the versions like \citep etc not working. Secondly I got the title of article to all lower case in the bibliography. Moreover, I would like to make the in text citations in blue font and hyperlinked. A lot of guidance available online on this topic but that is confusing or works only partially.

Any help please!

Answer 1

I will share my setup for working with APA style references. I do not know if it will answer all your concerns.

1. To keep capital letters in titles, you must enclose them in (double) braces {}. See Referencesx.bib

2. I found the biblatex and biber combination much more convenient and easier to work with.

3. Use \citep.

4. It is strongly recommended to load hyperref as the last package. It is highly configurable. I don't know if my setup is what you wanted, but it will put you on the right track.

Titles in double braces. Update To avoid incompatibilities that may arise with other styles, it is advisable to use the { } only in words or letters, not the full titles, as in

title = {{NASA} sends {MarsProve} to search for {L}a, {A}c, {T}h {P}a and {U} actinides to the {K}uiper belt},
