Hiya, I hope everyone is well!!

I just started my PhD program about a week ago and I have not met with my supervisor yet as he is ill with the flu. He suggested I start to read and assemble articles for my literature review. I have found relevant sources and am currently reading through the articles.

I just wanted to see if anyone has any advice in how I should be approaching these. I have gone through each method so far in depth and (although I am finding with some papers regarding PCR methods don't give the full details and some plasmids etc are not commercially available etc.) also the results.. I have already found a few gaps I could possibly address. I know most requirements for a literature review are similar. But I just wonder if I am going to far I don't want to lose focus. Also does anyone know where there would be some good examples??

Thanks!
