Recently, an article of mine got accepted in an Elsevier Journal. Since it was my first publication, I was not very much aware of the whole publication procedure. After acceptance of the paper, I got a link sent for gallery proof. At this stage, I found many grammatical mistakes in the paper, which I should have corrected during the revision stage. I have to agree that I was late regarding this matter. Yet, I incorporated all the extensive corrections and sent back the proof. The journal manager was helpful. He sent me a pdf file with all the corrections incorporated and asked me to approve the revised proof, which I did. Recently, I contacted Elsevier's customer support, whereby I got to know that the paper is in type-setting. It made me a bit confused because the pdf file I got from the journal manager was already corrected and type-setted.
So my question is how could be the paper in the typesetting stage if I have got a prepared pdf file of the revised proof for approval from the journal manager!! If anyone of you is familiar with this scenario, I would appreciate your feedback.
